The MC79M00 series of fixed output negative voltage regulators are
intended as complements to the popular MC78M00 series devices.
Available in fixed output voltage options of –5.0, –8.0, –12 and –15 V,
these regulators employ current limiting, thermal shutdown, and safe–area
compensation – making them remarkably rugged under most operating
conditions. With adequate heatsinking they can deliver output currents in
excess of 0.5 A.
